Sanitary Pressure Relief Valves A Sanitary Pressure Relief Valves is a type of self-acting device, designed for keeping tanks work properly. It can release air out of the tanks to maintain pressue, and also absorb air into tanks to be anti-vacuum. Sanitary Pressure Relief Valves including stainless steel sanitary pressure relief valves, food grade pressure relief valves, hygienic pressure relief valves, vacuum relief valves, air release valves. Kaysen Steel is a china manufaturer and supplier of stainless steel sanitary pressure relief valves, food grade pressure relief valves, hygienic pressure relief valves, vacuum relief valves, air release valves, we supply supperial quality stainless steel sanitary pressure relief valves,vacuum relief valves, air release valves in SS304, SS316, SS316L materials, size from 1/2"-4", DN15-DN100, connection types contains weld, clamp, thread types,etc Sanitary Pressure Relief Valves,Food Grade Pressure Relief Valves,Hygienic Pressure Relief Valves Kaysen Steel Industry Co., Ltd. , https://www.chinasanitaryvalve.com
First, avoid using inferior agents. It should be purchased from regular manufacturers and drug sales points to prevent counterfeiting, and pay attention to the date of manufacture and age of the drug and the reasonable storage and storage of the drug to prevent expiration. In addition, generally normal pharmaceutical products have a certain amount of bacteria, there should be no odor when opening the lid, and sometimes there will be citron (cultured material), while expired or fake products often produce odor or no smell. .
Second, avoid using at low temperatures. The active ingredients of bacterial biocides are protein crystals and living buds. Under low temperature conditions, the buds are slow to propagate in the pests, and the protein crystals are not easy to function. The ambient temperature is generally suitable at 10 to 35 ° C. If it is too low, it will affect the insect food intake, and the control effect is poor.
Third, avoid dry environment. The buds of bacteria in the bacterial bio-insecticides are in a humid environment. Therefore, the greater the humidity in the field, the higher the efficacy, especially the spraying of powdered biological pesticides should pay attention to the field humidity. Spray powder on the morning when there is dew in the morning and evening.
Fourth, avoid strong light. The ultraviolet rays in the sun have a killing effect on the buds, and if the light is intense, the ultraviolet rays will kill the bacteria. Therefore, spraying bacterial biocides should be carried out on cloudy or weakly illuminated ground. It is usually applied before 10 am or in the evening on a sunny day.
Fifth, avoid heavy rain. Soon after spraying the bacterial bio-insecticide, in case of heavy rain, the bacteria sprayed on the stems and leaves of the crop will be washed away to reduce the efficacy. However, if it is light rain after 5 hours of application, it will not only reduce the control effect, but also have a synergistic effect.
Sixth, avoid mixing with fungicides. Do not use fungicides when applying bacterial biocides
(such as carbendazim, thiophanate, etc.) mixed, otherwise it will easily lead to a serious reduction in the number of bacteria in the drug, thus affecting the insecticidal effect. Therefore, even a sprayer that has been sprayed with a bactericide should be rinsed before assembling a bacterial biocide.

Using bacterial biopesticides contraindicated
Bacterial biopesticides with insecticidal rate, do not pollute the environment, natural enemies of security, harmless to humans and animals, do not induce resistance to pests and other advantages, it is a new focus on promoting the use of pollution-free cultivation current protection agents, because of its control effect depending on the active agent in bacteria, so the use should pay attention to grasp the following points:
